If U-Boot is supplying a device tree, it should certainly make the
partition information match its own idea of the partitions.
For older non-device-tree away u-boot, I guess we'll have to make the
cuboot and treeboot wrappers mangle the device tree differently to
correct the partition information.
I suspect the easiest way to do this will be for the dts to contain
both treeboot and u-boot partition info, and have the wrapper delete
or nop the nodes for the other firmware.
